Question 1
Q1) A survey was made to find the type of music that a certain group of young people liked in a city. An adjoining pie chart shows the findings of this survey. From this pie chart, answer the following:
(i) If 20 people liked classical music, how many young people were surveyed?
(ii) Which type of music is liked by the maximum number of people?
(iii) If a cassette company were to make 1000 CD’s, how many of each type would they make?
Solution:
(i) 10% represents 100 people.
Therefore 20% represents = \frac{100\times20}{10}
10
100×20
= 200 people
Hence, 200 people were surveyed.
(ii) Light music is liked by the maximum number of people.
(iii) CD’s of classical music = \frac{10\times1000}{100}
100
10×1000
= 100
CD’s of semi-classical music = \frac{20\times1000}{100}
100
20×1000
= 200
CD’s of light music = \frac{40\times1000}{100}=400
100
40×1000
=400
CD’s of folk music = \frac{30\times1000}{100}=300
100
30×1000
=300
